Question
I’m not sure how to answer the first two as I don’t know what the difference between penetrating and non have an affect on. Would the non penetrating mean they can’t move so they stay the same in size? Also for E so help with that. D. You place a red blood cell into a hyperosmotic solution, containing non-penetrating particles. The cell will and the solution is considered tonic. You place a red blood cell into an iso-osmotic solution containing penetrating particles not present in the CF of the cell. The cell will and the solution is considered -tonic to t E. Compartments A and B are separated by a semipermeable membrane as shown: a)Which compartment has a higher osmotic pressure? b) Which compartment is hypo-osmotic? c)Assuming only water can cross, which way will water move? d)Assuming the membrane also becomes permeable to Na+ (but not 0.02 M Na 0.03 M NaCI C-), which side of the membrane will become positively charged? e)How would your answers to questions a-c change if chamber B contained 0.03M of albumin instead of NaCI?Explanation / Answer
Hyperosmotic solution means the osmolarity of solution is high i.e, it has high concentration of substances(polar, non-polar), here the substances are non- penetrating i.e, they will not cross across semipermeable membrane. One of the reasons for nonpentrability is large size of solutes.Tonicity is influenced by nonpenetrating substances.More number of solutes outside cells- solution is hypertonic.
The red cells will shrink and solution is considered hypertonic.
Water moves from its high concentration to low concentration i.e, from hypotonic solution to hypertonic solution. Hypotonic solution has more water and less solutes.
The term iso means same, iso osmolar means both the solution and cells have same osmolarity. Here the question says the substances are penetrating, therefore they will move inside the red cells and hence the solute concentration outside cell will decrease - solution becomes hypotonic . Hence water from hypotonic solution moves inside cells causing them to swell.
